The installation was very easy. We were surprised at what little prep work we had to do. Harley showed up with everything they needed to remove the old windows and install the new ones. The workers took great care to not damage the building siding, and to make sure everything fit snugly without any gaps. Each window fit perfectly into each opening with almost no adjustments needing to be made. They also were very good at working within our strict homeowner's association rules about the exterior appearance of the building. At the end of the day we had beautiful new windows, and there was not a single scrap of material left behind. Over the last year we have had no issues with moisture, sound, or drafts with any of our windows. The sliding doors and windows track very well and seal perfectly. Our heating and cooling costs have gone down significantly (the old windows were single pane with aluminum frames). We currently don't have any of our heaters on at all, even in the coldest of winter. The heat from our downstairs neighbor is enough to keep us warm. Overall, I would give Harley a very good rating for having a very high quality product, superior service, professional installation, and all the while being very price competitive with great financing options.
